Document the <include> tag

[damithc]

Current: https://markbind.github.io/vue-strap/ does not document how to use the <include ... /> tag

[acjh]

<include ... /> is a MarkBind construct though.
It's documented in https://github.com/MarkBind/markbind-cli/wiki/Including-contents.

I see. I don't think end users need to know there are two types of syntax. It would be good to document all syntax in one place, at least a summary.

[damithc]

It would be cool if MarkBind itself can solve this problem of integrating documentation of markdown, vue, and markbind. :-)

Sounds suitable for #135
